Cells were seeded in 6-well plates at a density of 1 × 10^6 cells per well and allowed to adhere overnight. To induce inflammation, cells were treated with 1 µg/mL lipopolysaccharide (LPS) for 24 hours. Concurrently, cells were exposed to varying concentrations of rutin (10 µM, 20 µM, and 50 µM) to assess its anti-inflammatory effects. After treatment, cell supernatants were collected, and the levels of inflammatory cytokines (TNF-α, IL-1β, and IL-6) were measured using enzyme-linked immunosorbent assays (ELISA). Cell viability was assessed using the MTT assay to ensure that rutin concentrations used did not induce cytotoxicity. In Vivo Studies: Adult male Sprague-Dawley rats (weight 250-300 g) were used for the dorsal spinal cord injury (DSCI) model. Rats were anesthetized with intraperitoneal injections of ketamine (80 mg/kg) and xylazine (10 mg/kg). A laminectomy was performed at the T10 vertebral level, and the dorsal spinal cord was exposed. DSCI was induced using a weight-drop impactor (10 g weight dropped from a height of 25 mm). Post-surgery, rats were randomly divided into three groups: sham-operated (control), DSCI + vehicle (saline), and DSCI + rutin (50 mg/kg/day, intraperitoneal injection).

Disease progression is associated with high neurologic impairment risks, which must be weighed against the morbidity risks of treatment by gross total resection (GTR), the current standard of care. Given the rarity of these tumors, data on immediate postresection neurologic changes are limited in scope and generalizability.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;PURPOSE&lt;/h3&gt;&lt;div&gt;We evaluated the predictive value of several perioperative factors on immediate postoperative neurologic outcomes in patients with IMSCTs. Identifying significant predictors of neurologic deficits and improvements can refine pre-surgical risk estimation for treatment determination and patient counseling in a shared decision-making model.

Univariate associations and clinical expertise were jointly utilized for multivariable model selection, with Akaike information criterion (AIC) used to assess model fit. Violin, deviation, waterfall, and coefficient plots were used for visualization.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;RESULTS&lt;/h3&gt;&lt;div&gt;A total of 67 patients were included, with a median age of 51 years (interquartile range [IQR]) 31-64). 21 (31%) patients were female, and locked facet was bilateral in 39% (N=26). Mechanism was high-energy trauma (motor vehicle collision or fall from height) in 67% (N=42). Modified 5-factor frailty index (MFI-5) score was 0 in 69%, 1 in 21%, and 2 or greater in 10%.

However, its impact on postoperative outcomes, particularly in the context of spinal surgeries, remains uncertain. While studies on lumbar fusion procedures have yielded mixed results, some suggest that semaglutide may influence bone turnover and muscle mass, which could affect the healing process following spinal fusion. One study indicated an increased risk of requiring additional surgeries post-transforaminal lumbar interbody fusion (TLIF). In contrast, others noted reduced complications following single-level posterior lumbar fusion, including fewer emergency department visits and adverse events. These inconsistencies point to the need for further research to clarify the effects of semaglutide on surgical outcomes in spinal fusion procedures, specifically in the context of anterior cervical discectomy and fusion (ACDF).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;PURPOSE&lt;/h3&gt;&lt;div&gt;The purpose of this study is to evaluate the impact of semaglutide on 90-day and 2-year surgical and medical complications in diabetic patients undergoing ACDF.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;STUDY DESIGN/SETTING&lt;/h3&gt;&lt;div&gt;A retrospective cohort study.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;PATIENT SAMPLE&lt;/h3&gt;&lt;div&gt;N/A&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;OUTCOME MEASURES&lt;/h3&gt;&lt;div&gt;N/A&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;METHODS&lt;/h3&gt;&lt;div&gt;A retrospective cohort study was conducted utilizing the TriNetX research network, a comprehensive healthcare database. Diabetic patients undergoing ACDF were divided into two groups based on their use of semaglutide: Cohort 1 (patients prescribed semaglutide at the time of surgery) and Cohort 2 (patients with no history of semaglutide use). Propensity score matching was applied to balance the two groups' baseline demographic and clinical characteristics. Surgical and medical outcomes, including both early (90-day) and long-term (2-year) complications, were compared between the two cohorts. The primary outcomes assessed were major medical and surgical complications, and the risk ratios (RR) were calculated for each complication at both 90-day and 2-year intervals.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;RESULTS&lt;/h3&gt;&lt;div&gt;At the 90-day postoperative mark, no significant differences were found between the two groups for any of the complications analyzed. However, at the 2-year follow-up, semaglutide use was associated with a significant reduction in three major complications: mortality, pseudarthrosis, and general postoperative mechanical complications. Specifically, semaglutide use was linked to lower odds of mortality (2.6% vs 5.2%, RR = 0.487, 95% CI = 0.253 - 0.935, P = 0.028), a decrease in pseudarthrosis rates (6.7% vs 12.9%, RR = 0.487, 95% CI = 0.319 - 0.743, P = 0.001), and a reduction in general post-operative mechanical complications (11.4% vs 17.8%, RR = 0.596, 95% CI = 0.421 - 0.843, P = 0.003).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;CONCLUSIONS&lt;/h3&gt;&lt;div&gt;The","PeriodicalId":49484,"journal":{"name":"Spine Journal","volume":"25 11","pages":"Page S21"},"PeriodicalIF":4.7,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Historically, standard threaded screws were used; however, a novel 3D-printed porous threaded implant (PTI) has emerged to induce osseointegration. Limited literature exists on insertional and pullout characteristics, especially for revision.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;PURPOSE&lt;/h3&gt;&lt;div&gt;Therefore, this study investigated the re-insertional torque and pullout strength across various PTI dimensions and conditions.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;STUDY DESIGN/SETTING&lt;/h3&gt;&lt;div&gt;Biomechanical.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;PATIENT SAMPLE&lt;/h3&gt;&lt;div&gt;N/A&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;OUTCOME MEASURES&lt;/h3&gt;&lt;div&gt;N/A&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;METHODS&lt;/h3&gt;&lt;div&gt;Mechanical testing (ASTM F543) was conducted to evaluate insertional torque and pull-out strength. Using 10 and 20pcf (lbs/ft3) polyurethane blocks, the TORQ iFuse Implant (SI-Bone, Santa Clara, CA) was tested. A 10 × 35mm PTI served as the control. For subsequent tests, the 10 × 35mm PTI was removed, and varying diameters (10, 11.5, 12.5mm) and lengths (35, 40, 45mm) were reinserted. The maximum and final insertional torque and the maximum axial pullout load were measured. Reinsertion followed two conditions: direct and with tapping. ANOVA techniques with pairwise comparison and Pearson correlation tests between insertional torque and pullout force were performed (α=0.05).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;RESULTS&lt;/h3&gt;&lt;div&gt;Significant effects and interactions were observed for PTI size, bone density, and tapping. Independent of density and tapping, maximum insertional torque was significantly less than the control for the similar size PTI (10 × 35, 10 × 40; p&lt; 0.001) and significantly greater for large PTIs (11.5 × 40, 11.5 × 45, 12.5 × 35, 12.5 × 40, 12.5 × 45; p&lt; 0.012). Pullout force was significantly less than the control for short PTIs (10 × 35,11.5 × 35,12.5 × 35; p&lt; 0.028) and significantly greater for long PTIs (11.5 × 45; p&lt; 0.001). Independent of size and tapping, the denser bone was significantly greater for maximum insertional torque (20 vs 10pcf | 929.1±6.5N vs 235.0±6.5N·cm; p&lt; 0.001) and pullout force (20 vs 10pcf | 1331.2±14.8 vs 457.3±14.6N; p&lt; 0.001). Independent of size, tapping showed a significant increase for maximum insertional torque (‘tap’ vs ‘no tap’ | 1063.6±9.2 vs 794.5±9.2N-cm; p&lt; 0.001) and pullout force (1799.1±20.9 vs 863.4±20.9N, p&lt; 0.001) with the denser bone; however, a significant decrease was shown for pullout force (399.7±20.6 vs 514.9±20.6N; p&lt; 0.001) with the less dense bone. Final insertional torque trends matched those for maximum insertion torque except for 20pcf foam without tapping, which was substantially less with increased diameters. Pullout force was shown to be correlated to maximum (r=.829; p&lt;.001) and final (r=.946; p&lt;.001) insertional torque across all conditions.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;CONCLUSIONS&lt;/h3&gt;&lt;div&gt;Increased PTI lengths equated to greater engagement, but e","PeriodicalId":49484,"journal":{"name":"Spine Journal","volume":"25 11","pages":"Page S45"},"PeriodicalIF":4.7,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
